I'm Leo, owner of LC Heating & Air. I've spent years working on hillside custom homes with tight-access mechanical areas. I know that when conditioned air leaks into your attic or wall cavities, you're paying to heat or cool spaces you don't even use. My goal is to give you a clear, honest assessment of your duct system so you can decide if sealing is the right move for your home.

Why Hillside Homes Often Need Duct Sealing
In our area, the combination of canyon topography and custom housing stock creates specific challenges. Many homes here have long duct runs, tight attic spaces, and older flex duct that can easily get crushed or disconnected during other home repairs. When ducts leak in these inaccessible areas, you lose a significant portion of your conditioned air before it ever reaches your living room.
I often see systems where the return air is pulling from hot attic spaces or garages because of unsealed plenums. This doesn't just waste energy; it forces your HVAC system to work much harder than it should, which leads to premature wear on your blower motor and compressor. If you notice unusual dust buildup near your registers or your energy bills seem high for your home size, it is time to look at the ducts.
Understanding Your Duct System
Chevy Chase Country Club features a mix of custom homes with varied system ages. Whether you have original sheet metal ductwork or newer flex duct, the joints and connections are the most common failure points. Over time, the mastic or tape used during the original installation dries out, cracks, and falls off.
We don't believe in one-size-fits-all solutions. We look at your specific layout—whether it's a hillside property with difficult access or a home with limited attic space—to determine the best way to seal your system. We prioritize the areas where we can get the most impact for your investment.
Our Diagnostic Process
Before we suggest any repairs, we perform a duct blaster test. This is the only way to get real numbers on how much air you are losing. We pressurize your duct system and measure the leakage as a percentage of your total airflow.
This test takes the guesswork out of the equation. If your leakage is within a manageable range, we can focus on manual sealing. If the system is leaking significantly throughout, we might discuss Aeroseal as a more comprehensive solution. We provide you with the before-and-after results so you can see exactly what we accomplished.
Repair vs. Replacement: Making the Right Call
A common question I get is whether it's worth sealing an older system or if the whole thing should be replaced. If your ductwork is structurally sound but just leaky at the joints, sealing is a high-value repair that can extend the life of your current equipment. However, if the ducts are collapsed, moldy, or improperly sized for your current HVAC unit, sealing won't fix the underlying airflow issues.
I will always tell you if a repair is enough. If the pattern of your system's performance points to a larger issue, I'll explain why replacement might be the more cost-effective choice in the long run. My job is to give you the information you need to make a decision that makes sense for your home and your budget.
What to Expect Regarding Costs
Duct sealing costs vary based on the size of your home and the accessibility of your ductwork. Manual sealing for accessible sections typically ranges from $400 to $1,200, while Aeroseal internal sealing for a typical single-story home ranges from $1,500 to $3,000. These prices include the necessary duct blaster testing to verify our work.
We focus on providing a clear, written estimate before we touch any equipment. There are no hidden fees or surprises. When you consider that sealing can reduce your HVAC energy use by 15–25%, the work often pays for itself through lower utility bills.
Scheduling for Hillside Access
Working in Chevy Chase Country Club requires planning. We are familiar with the narrow canyon roads and the challenges of hillside equipment pads. When you call us, we'll ask about your access points and attic entry to make sure we arrive prepared with the right ladders and equipment.
We respect your time and your property. We aim to complete most residential duct sealing projects in a single day, minimizing the disruption to your home life.
Safety and Air Quality
Your indoor air quality is a priority. We use non-toxic materials for all our sealing processes. For Aeroseal, we use a vinyl acetate polymer that is safe and non-toxic. We recommend that you vacate the home for the 60–90 minutes it takes to complete the injection process, but you can return as soon as we're done.
We also ensure that our work complies with California Title 24 standards. This isn't just about following the rules; it's about ensuring your system is safe, efficient, and properly documented.

Is Duct Sealing Right for You?
If your home feels like it has 'hot spots' or 'cold spots,' or if your energy bills seem unusually high, it's worth having us out for a diagnostic. We don't push for unnecessary work; we look for the root cause of your comfort issues.
If we find that your ducts are in good shape but just need a little attention at the joints, we'll handle it. If we find that the system is beyond repair, we'll be upfront about it. Call LC Heating & Air at (323) 970-3113 to schedule a visit.
How the visit works
We perform a duct blaster test to quantify existing leakage as a percentage of system airflow.
Based on leakage quantity, duct type, and accessibility, we recommend manual sealing, Aeroseal, or a combination.
We apply mastic to all accessible joints and plenums, or set up and run the Aeroseal process for internal sealing.
We re-run the duct blaster test and provide you with before/after leakage numbers as written documentation.
